No. l34,650 for INCIN- ERATING COMMODE, filed Apr. 16, 1971.

BACKGROUND OF THE INVENTION This invention relates to an apparatus for use in disposing of human waste and, more particularly, is concerned with a waste comminuting means for use in a combustion chamber operatively associated with an incinerating commode.

In the field of human waste disposal, a number of methods have been employed for disposing of the solid and liquid waste. Commonly, sewage treatment plants are provided which are connected by sewage pipe lines to domestic and commercial facilities. As population has increased, the capabilities of the sewage treatment plants have been severely strained and many such plants have been unable to satisfactorily process the increased waste of the community. such inadequacy of sewage plant facilities has necessitated the expansion of the facilities at great expense to the taxpayers. In addition, the inadequacy of the sewage treatment facilities has also led to the pollution of streams and rivers normally used for water supply in recreation facilities.

In remote areas where sewage treatment facilities are not available, septic tank means are often employed to dispose of human waste. A septic tank utilizes bacterial action in the tank to dispose of solid waste and utilizes a subterranean field of disposing of the liquid waste. However, in'certain areas where the soil conditions are not satisfactory, utilization of septic tanks creates unhealthy conditions intheiruse. A number of municipalities have adopted strict codes to regulate the use of septic tanks.

In remote areas where a sewage treatment facility is not available and wherein septic tanks are not feasible, oxidation ponds are employed to dispose of human waste. In utilizing oxidation ponds, a fungus is utilized to dispose of the solid waste with the liquid waste being disposed of through evaporation or surface drainage means. The use of oxidation ponds requires a large ground area and is unattractive in appearance.

A number of attempts have been made todevise chemical and incinerating commode facilities for dis- I posing of human waste. However, the prior art chemical and incinerating waste disposal apparatus are extremely complex in construction and operation, uneconomical to manufacture and unreliable in performance.

SUMMARY OF THE INVENTION The above indicated disadvantages of the prior art have been overcome by the present invention which basically includes an upwardly open commode body disposed above a combustion chamber wherein the human waste can be deposited in the commode body and allowed to fall by gravity :into the combustion chamber. The combustion chamber includes waste comminuting means for reducing the particle size of human waste to be incinerated and includes heat source means operative for incinerating the comminuted human waste.

The incinerating commode of the present invention includes blower means and confined passageway means defined around the combustion chamber whereby a cooling medium can be introduced therein for cooling the combustion chamber during an incinerating operation.

The blower means operatively associated with the combustion chamber for effecting a cooling operation also includes passageway means communicating with the interior of the combustion chamber forpurging the combustion chamber of unwanted gases and byproducts of combustion.

It is therefore a primary object of the present invention to provide an incinerating commode effective for disposing of human waste.

Another object of this invention is to provide an incinerating commode whereby the [human waste can be transferred from the commode body to the combustion chamber by gravity.

A further object of this invention is to provide means for cooling the combustion chamber during an incinerating operation. I

A still further object of this invention is to provide an incinerating commode having means for reducing the particle size of waste to be incinerated.

Yet another object of this invention is to provide an incinerating commode having cyclically operable means for transferring the ash by-products of combustion from the combusition chamber to a filter collection means.

Another objectof this invention is to provide an incinerating commode having a confined cooling passageway surrounding the combustion chamber with cyclically operable control means operable for effecting a flow of cooling air in the confined passageway during a combustion operation and operable for effecting a flow of air through the combustion chamber to transfer ash therefrom in response to completion of a combustion operation.

Still another object of this invention is to provide an 7 incinerating commode having an air chamber located between a commode body and combustion chamber and including selectively operable closure means operable for initiating an incinerating operation and cyclically controlled for movement to an open condition in response to completion of an incinerating operation.

A still further object of this invention is to provide an incinerating commode having selectively operable dispensing means for dispensing a flushing fluid into the commode body.

Another object of this invention is to provide an incinerating means operatively associated with a commode body and including means for automatically purging combustion chamber of both gas and ash byproducts of combustion in response to completion of an incinerating operation.

An additional object of this invention is to provide an incinerating commode operable for the disposal of human waste which is simple in construction and operation, economical to manufacture and reliable in performance. I

These and other objects and advantages in the details of construction will become apparent upon reading the following description of the illustrative embodiments embodying the principles of the present invention, with reference to the attached drawings wherein like reference numerals have been used to refer to like parts throughout the several figures, and wherein:

 7. An incinerating commode as required by claim 6 further characterized in that said heat source means is supported in said conduit means whereby pressurized air flowing therethrough will develope pressurized heat source means within said combustion chamber.
 8. An incinerating commode as required by claim 1 further characterized in that said means for reducing the particle size of waste deposited therein includes a plurality of fixed comminuting blades and a plurality of rotatable comminuting blades, and wherein said fixed comminuting blades are supported from said combustion chamber and extend radially toward the center of said combustion chamber and wherein said rotatable comminuting blades are supported by a vertically oriented support shaft, rotatably operable in said combustion chamber, with said fixed comminuting blades being vertically spaced relative to each other and with said rotatable comminuting blades being vertically spaced between adjacent fixed comminuting blades whereby rotation of said rotatable communiting blades will cooperate with said fixed comminuting blades to effectively reduce the particle size of waste deposited therein.
 9. An incinerating commode as required by claim 8 further characterized in that rotation of said rotatable comminuting blades is effected by pressurized air means developed in said combustion chamber.
 10. An incinerating commode as required by claim 9 further characterized in that said means for reducing the particle size of waste deposited in said combustion chamber includes a base support plate having a plurality of apertures formed therein and wherein said rotatable brush means is operatively associated with said support plate and said apertures for effectively brushing the surface of said plate to cause the ash by-products of combustion to drop through said apertures.
